The Versatile Spring-Return Single-Acting Hydraulic Cylinder for Lifting Tables
Expanded Introduction
Spring-Return Single-Acting Hydraulic Cylinder is a hydraulic cylinder that uses hydraulic oil to expand the piston. When pressure is released, the built-in spring automatically retracts the piston.
Design and Construction Characteristics
- Single-Acting Structure: Hydraulic oil pressure is used for extension, while the return is dependent on the built-in spring.
- Spring Selection: Choose an appropriate spring for quick and complete reset after pressure release.
- Sealing Design: High-quality materials prevent oil leakage and ensure system efficiency.
- Strength and Durability: High-strength steel is used to withstand high pressure and impact.

Construction and Assembly Process
The assembly process requires precision to ensure proper component alignment, especially for the piston and cylinder block. Welding and strong mechanical connections prevent oil leakage under pressure.
Working Principle
The single-acting mechanism uses hydraulic pressure for extension and spring force for retraction. This cycle ensures efficient operation of the hydraulic cylinder.
Types and Configurations
There are three main types of spring-return single-acting hydraulic cylinders, each designed for specific applications, such as lifting tables, with unique configurations to meet various needs.
